Résumé:
This paper studies the multi-carrier two-user Gaussian Interference
Channel (G-IFC) with an adaptive strategy depending
on the channel gains. The decoding strategy at each receiver is
either Successive Interference Cancellation or treating interference
as noise, depending on whether interference is strong
or weak. The transmit strategy may also rely on FDMA when
required. Then, an iterative power allocation algorithm is proposed
in order to maximize the sum rate when considering all
carriers jointly. By splitting power allocation at both transmitters,
the initial optimization problem can be turned into a
series of convex optimization problems. The proposed algorithm
converges very rapidly and provides a sum rate increase
compared to FDMA and to a strategy where interference is always
considered as noise.
